数的大小比较一直是数学学习的一个重要方面.可是在中学数学学习中,除了初一时学习了利用数轴比较数的大小之外,很少涉及.但在学习数学的过程中,比较两个数孰大孰小的问题却常出现.现在我们就探讨如何比较一些正数的大小. Comparison of the size has been an important aspect of mathematical learning, but in the secondary school mathematics learning, except for the first time to learn the use of the number of comparison of the number of axes, rarely involved, but in the process of learning mathematics, the two numbers The bigger the problem is, the smaller the problem is, and now we explore how to compare some positive numbers.
